mds: fix revoking caps after after stale->resume circle

After session stale->resume circle, client thinks its caps get lost. But
MDS may keep some client caps untouched. To revoke untouched caps, MDS
needs to re-issue them to client, then do revocation. If MDS skips the
're-issue' step, client will not response to the cap revoke.
